If the car is equipped with Sensus Navigation*, speed information is read from the navigation unit in the following cases:
- On detection of signs that indirectly indicate a speed limit, such as motorway, dual carriageway and city limit signs.
- If a previously detected speed sign is assumed not to apply any longer, but no new sign has been detected.
In certain markets, the Road Sign Information function* is only available in combination with Sensus Navigation*.
If a downloaded third-party app is used for navigation then there is no support for speed-related information.
